spinose, the anterior unarmed. Primaries trigonate, stumpy in ap- 

 pearance, the apex somewhat marked in the male, rectanguhir in 

 the female. Vein 5 of the secondaries is only a little weaker than 

 the others. 



The generic name was proposed by Mr. Grote in Mr. Neumoegen's 

 collection, but has not been sanctioned by any description so far as I 

 can find. I believe the genus to be a good one, hence describe it 

 under the name proposed by Mr. Grote. It has some of the ap- 

 pearance of certain species of Perigia, but is more stumpy winged, 

 and has the lengthily pectinated male antennae, which distinguish 

 the genus from anything of otherwise similar structure. 



Eupolia licentiosa n. sp. (PI. iii, fig. 8) — Ground color ashen gray, pow- 

 dery. Head and thorax coucolorous, immaculate; but the ground mixed with 

 luteous scales, which lighten the tip of the collar and the disc of the patagiae. 

 Primaries with all the niaculation uonfnsed, mottled and broken. The basal and 

 t. a. lines, while they are indicated and apparently geminate, are yet so con- 

 founded with the powdery ground that it is impossible to describe them. The 

 t. p. line is somewhat better marked, outcurved over the reniform and some- 

 what incurved below; outwardly projected on the veins, which are blackish, 

 through the somewhat luteous tinted suhterminal space. S. t. line fairly evi- 

 dent, luteous. rather evenly sinuate, better defined by black scales on both sides. 

 A broken, black terminal line: a pale line at the base of the fringes, which have 

 also a pale central line. The claviform is small, coucolorous, outlined by black 

 scales, which are not at all distinct superiorly, but form a rather obvious line 

 inferiorly, and thereby the only decided bit of maculation on the wing. Both 

 the ordinary spots are large, white powdered, not defined, and only incompletely 

 traceable. Secondaries white in both sexes, with a small black discal spot; in 

 the male there is a blackish powdering along the outer margin, which, in the 

 female, forms an indefinite, rather broad outer baud. Beneath white, powdery, 

 with a small discal spot on both wings, and traces of an outer line; both much 

 more distinct in the female. Expands 27.5-29 mm. ; 1.10-1.15 inches.

One pair in good condition are before me. With the female alone 

 at hand, there may be some difficulty in placing the insect; but 

 where both sexes can be examined, there will be no trouble. This 

 is one of those obscure forms, the description of which is bound to 

 be unsatisfactory, botli to the describer and to the student who may 

 try to use it. 



Polia resoluta n. sp. (PI. v, fig. 5) — Ground color varying from almost 

 while to bluish ash-gray, black powdered. Head with a black frontal line. 

 Collar with a black, somewhat diffuse line above the middle; patagife with a 

 blackish submarginal line, most evident in the paler specimens. Primaries with 

 a blackish longitudinal shade through the middle of the basal space, and a some- 

 what darker terminal space. A luteous blotch over the reniform. Median lines
